Masunaga KOUKI 108 Eyeglasses by Masunaga. Color: 23 BR, 19 BK, Size: 52-20-145. 108’s wellington-shaped, edgy topline creates a smart look. The icon made up of solid washer and hex screws accents and tightens the frame. A temple core with geometric patterns engraved on the motif of a fractal structure. Unlike crimping and embedded styles, the carved parts are screwed in place, giving you a sense of attention to detail.
